+ * NAME
+ *  plugin_dispatch_multivalue
+ *
+ * SYNOPSIS
+ *  plugin_dispatch_multivalue (vl, 1,
+ *                              "free", 42.0,
+ *                              "used", 58.0,
+ *                              NULL);
+ *
+ * DESCRIPTION
+ *  Takes a list of type instances and values and dispatches that in a batch,
+ *  making sure that all values have the same time stamp. If "store_percentage"
+ *  is set to true, the "type" is set to "percent" and a percentage is
+ *  calculated and dispatched, rather than the absolute values. Values that are
+ *  NaN are dispatched as NaN and will not influence the total.
+ *
+ *  The variadic arguments is a list of type_instance / gauge pairs, that are
+ *  interpreted as type "char const *" and "gauge_t". The last argument must be
+ *  a NULL pointer to signal end-of-list.
+ *
+ * RETURNS
+ *  The number of values it failed to dispatch (zero on success).
